Holland House, originally known as Cope Castle, was an early Jacobean country house in Kensington, London, situated in a country estate that is now Holland Park. It was built in 1605 by the diplomat Sir Walter Cope. The building later passed by marriage to Henry Rich, 1st Baron Kensington, 1st Earl of Holland, and by descent through the Rich family, then became the property of the Fox family, during which time it became a noted gathering-place for Whigs in the 19th century. The house was largely destroyed by German firebombing during the Blitz in 1940 and today only the east wing and some ruins of the ground floor and south facade remain, along with various outbuildings and formal gardens. In 1949 the ruin was designated a grade I listed building and it is now owned by the Royal Borough of Kensington and Chelsea.

The Jacobean style is the second phase of Renaissance architecture in England, following the Elizabethan style. It is named after King James VI and I, with whose reign it is associated. At the start of James' reign, there was little stylistic break in architecture, as Elizabethan trends continued their development. However, his death in 1625 came as a decisive change towards more classical architecture, with Italian influence, was in progress, led by Inigo Jones. The style this began is sometimes called Stuart architecture, or English Baroque.
